(TRUNEWS) While reviewing 9/11 documents previously declassified in July 2015, blogger Brian P. McGlinchey discovered a new link between Saudi Arabia and the 2001 terror attacks.

In the seventeenth of the 29 documents released under the Interagency Security Classification Appeals Panel (ISCAP) appeal 2012-48, McGlinchey uncovered that the FBI had located the flight certificate for Ghassan Al-Sharbi — a known al-Qaeda member who trained with the 9/11 hijackers. The report said the Embry Riddle certificate was buried in an underground cache in Pakistan, and was inside an official envelope marked from the Saudi Embassy in Washington.

McGlinchey noted on his blog, 28pages.org that its not uncommon for people to re-use envelopes or to correspond with their nations embassy while living in a foreign country. But did say nonetheless, that this — and the rest of Document 17 — directly indicates another possible connection between the Saudi government, al-Qaeda, and the 9/11 terrorist attack.
